Summary:
Researchers from Rudolf Jaenisch’s lab at the Whitehead Institute for Biomedical Research have taken a significant step toward answering a half century old question—do clones, like Dolly, derived from adult cells develop from a fully mature adult cell or do they develop from rare stem cells found in adult tissues? The researchers have proved for the first time that fully differentiated adult cells can form clones, but they found the process is extremely inefficient. It is more likely that elusive adult stem cells, which exist in tiny numbers along with the mature adult cells, are actually the ones to form clones, says Jaenisch.
